[Objective] The study aims to identify and describe a new species Cinnamomum huae (Lauraceae), which collected from Nanjian, Yunnan in Southwest China. [Methods] This species was confirmed as a new taxa by morphological comparison with morphologically similar species and molecular phylogenetic study based on chloroplast genome data with related species. [Results] The new species is similar to C. chago in pinnately veined, leaves opposite or subopposite, long acumen, but differs in current year branchlets sparsely puberulent, terminal bud densely pubescent, leaf blade gray green abaxially and puberulent, margin undulate and fruit oblate. The chloroplast genome size of this species is 15 4078 bp, 1 325 bp longer than C. chago and 1 348 bp longer than C. pittosporoides, which has being an extra 678 bp fragment in the inverted repeat region.compared to C. chago and C. pittosporoides. In the phylogenetic tree constructed using maximum likelihood method based on whole chloroplast genome of 35 Lauraceae species, C. huae formed independent parallel branches with C. pittosporoides and other species. [Conclusion] Both the morphological and phylogenetic research indicate C. huae should be a distinct species.
